Steps of reproduction

1. run picom with defined config file
2. open a terminal window (Wezterm) and a browser window
3. switch to the terminal window

Expected behavior

The terminal is opaque with the defined opacity and shows the wallpaper as a background.

Current Behavior

The terminal is opaque with the defined opacity but shows the underlying browser window as background.
